Abstract (en)

An image reading device includes a charge-coupled device (4) that generates and outputs an image signal, a timing generator (3) that outputs a frequency-modulated clock, a modulation signal detector (10) that detects a modulation signal being a signal corresponding to a change in frequency of the clock, an amplitude controller (11) that controls an amplitude of the modulation signal, and a signal combining unit (8) that superimposes the modulation signal after the amplitude is controlled on the image signal.
